A pair of oppositely oriented cylinders are telescopically arranged to contain an assembly of piston, plunger and springs. One of the cylinders carries a recoil pad, and the other cylinder is mounted within the butt end of a firearm stock. Recoil forces are interrupted in their transfer to the recoil pad by operation of the assembly.

A recoil reducing mechanism for firearms of the type which have a stock supporting a barrel and trigger at the fore end of said stock and a recoil pad at the butt end of said stock, said barrel having a first longitudinal axis which is approximately parallel a second axis, said second axis constituting the major axis of said stock so that recoil forces resulting from the discharge of said firearm act upon said recoil pad, the improvement which comprises: a first hollow cylinder mounted substantially within said stock approximately parallel said first longitudinal axis, said first cylinder having a first end oriented towards said barrel and a second end in open communication with the exterior of said butt end of said stock; a second hollow cylinder with a first end carrying said recoil pad and a second end inserted through said second end of said first cylinder so that said second cylinder is reciprocably mounted within said first cylinder along a third axis, said third axis constituting the common longitudinal axis of said first and second cylinders, whereby said recoil forces act upon said recoil pad through said first and second cylinders, thereby urging the respective said first ends of said cylinders towards each other; force transfer means mounted within said first and second cylinders, including: a piston mounted concentrically and reciprocally with respect to said third axis, said piston element having a first end and a second end, first biasing means mounted between said first end of said piston and a said first end of one of said cylinders, thereby to urge said second end of said piston towards the second end of said one of said cylinders, second biasing means mounted between the first end of the other said cylinder and a reaction surface isolated from said piston, thereby to urge said first ends of said cylinders away from each other, a plunger element mounted in association with said second biasing means, said plunger having a first end bearing upon said first end of said other said cylinder and a second end normally bearing upon said first biasing means, interruption means operably associated with said second end of said plunger and said second end of said piston, said interruption means being operable, as said first ends of said cylinders move towards each other in response to recoil forces, to move said second end of said plunger out of contact with said second surfaces of said piston, thereby permitting said plunger to advance cushion means associated with said piston mounted for contact by said second end of said plunger as said plunger advances towards said first biasing means, thereby stopping further such advancement; and travel limiting means operably associated with said first and second cylinders to restrict the separation of said first ends of said cylinders under the influence of said first and second biasing means in the absence of recoil forces.
